Boston Red Sox's Mike Napoli, right, celebrates his three-run home run with David Ortiz, left, who scored on the homer, in the third inning of a baseball game against the New York Yankees in Boston, Sunday, July 21, 2013.

BOSTON — Mike Napoli's teammates weren't so concerned about what he did in the middle innings after his two home runs — one to start things off, the other to finish it.

Napoli hit a three-run shot after the Red Sox fell behind early, then he ended the game with a solo shot with two outs in the 11th inning, and Boston beat the New York Yankees 8-7 on Sunday night.

"He's a dangerous batter," Red Sox catcher Jarrod Saltalamacchia said. "He can do damage at any point in the game."
